X-RAY TERMINAL.

Application led September 23, 1921. Serial No. 502,700.

T 0 all whom it may concern Be it known that I, EDWARDFAQVVAGNER,

a citizen of the United States, residing at yFort lVaync, county of Allen, State of Indiana, have invented certain new and useful Improvements in X-Ray Terminals, of which the following'is a specification.

My invention relates to terminals for electrical apparatus and is more particularly concerned with terminals adapted for use with transformers designed for X-ray service.

The general object. of my invention is the provision of a terminal of this nature which shall be :1s simple in construction asA is consistent with eliiciency in operation and in which the different parts may be easily assembled and disassembled so that parts which may be found to have detects during the process of manufacture and test or while in use may be discarded and replaced Without discarding the entire terminal.

One embodiment of my invention is il lustrated in the accompanying drawing in which Fig. 1 shows an X-ray transformer equipped with a terminal constructed in accordance with my invention; Fig. 2 shows a longitudinal sectional view of one of the terminals; Fig. 3 is a .view of the sphere the direction of the arrow, A of Fig. 2; Fig. 1 is a side view of the sphere with a portion broken away on the line B of Fig?) and looking in the direction or' the arrow; and Fig. 5 is a longitudinal sectional view of the socket shown in Fig. 2.

In the embodimentY of the invention shown in the drawing, the terminal includes a hollow tubular stem portion 1 formed with a longitudinal opening to accommodate the conductor elements of the terminal. Built into the lower end of the stem 1 is a metal sleeve 2 which forms a metallic lining for the stem. The stem 1 is formed of some suitable insulating material such as the phenol condensation product known as bakelite which may be moulded around the sleeve 2 so that both are sebcurely and permanently united. A flange 3 is formed on the stem 1 which is secured to the top or cover 4 of the transformer by a nut 5, a gasket 6 being provided under the Harige 3. v

is commonl in X-ray transformers to pro# vide one terminal carrying a single conductor and a second terminal carrying two conductors so that one terminal, such as the terminal 11 shown in Fig. 1, would have a single socket and the other terminal would have twosockets as shown most clearly in Fig. 3. rIhe terminal illustrated in detail in the drawing is constructed with two sockets. Flexible conductors` ending in plugs which fit these sockets may be used to connect the terminal conductors to other apparatus. A sleeve `12 of conducting material is threaded into the hub 8 of the sphere and:` fits into the sleeve 2 as far as or slightly beyond its lower end. Inside the sleeve 12 isa rod 18 of conductive material held in place and insulated from the sleeve by insulating bushings 14 and 15 and some suitable-insulating cement 16. Two sockets 17 and 18 are screw-threaded into the sphere 7, the socket 18 being insulated from the lsleeve by a bushing 19. A vconnecting link 2O joins the socket 18 and the rod 13.

Clips Y21 and 22 are provided for connecting transformer leads to the rod 13 and sleeve` l12 respectively.

During the process of manufacture; the terminal is first' assembled in two units one of these units includingthe stem 1 and the sleeve 2 and theother unit includingthe socket 17 and' from the' other transformer lead it is through the clip 21, rod`13, link 20 and socket 18.

If any defects appear during factory tests, or if any develo while the terminal vis in use afterwards, t e joint between the it may be discarded and replaced by a new l States part, the part which is not defective beingl saved in either case. The construction of the terminal is also `such that it may be usedin connection with an oil-filled transformer casingwith practically no danger of leakage. of oil through theI lterminal or around its base.

What I claiml asnew and desire to secure by Letters Patent. of the United 1s,- 1f 1. Iii aterminalfor electrical apparatus, a tubular stem, a conducting sleeve enclosed in the stem, a conductor within the sleeve v.and insulated therefrom, the conducting sleeve and conductor being each arranged for connection with electrical apparatus at each end, and the conducting sleeve being secured to the stem near one end only,

whereby the conducting sleeve and conductor may beremoved from the stem by disconnecting it near one end.

2. In av terminal for electrical apparatus, a tubular stem including an outer insulating portion and a conducting sleeve moulded into one end thereof, two conductors within said stem and insulated from each other,

one of vsaid conductors f surrounding the low conducting member through the stem and secured to the stem at its opposite end only, and a conductor extending from the space within said hollow conducting member to` the opposite end of said conducting sleeve and insulated from said member and sleeve, said 'hollow conducting member, the opposite end of said sleeve and eac-h end of said conductor being` arranged for connection with electrical apparatus.

In witness whereof, I have hereunto set,

my hand this 19th day of September, 1921.

EDWARD A.'wAGNER.
